Lin Mo, an orphan, receives the barren Luoyan Valley as his share of the family estate. By chance, he discovers geothermal hot springs and devotes himself to cultivating rare winter vegetables. Upholding his contracts and running his business with integrity, he partners with Su Ruo, an intelligent female physician, to manage their enterprise. When his greedy elder uncle tries to seize their property and spread malicious rumors, Lin Mo clears his name with the county government's official land deed, physical evidence, and the fair judgment of the authorities. Through a lawful agricultural business built on hard work and proper rules, he secures his livelihood and earns both success and a good reputation.
